netty failed to initialize a channel 当使用Netty构建应用程序时,可能会遇到“Netty初始化通道失败”的错误。这个问题可能会在以下情况下发生: 1.端口被占用:如果所选端口已经被其他应用程序占用,Netty将无法初始化通道。您可以尝试更改端口或停止其他应用程序以释放端口。 2.防火墙阻止连接:如果您的防火墙设置不正确,...

至于不同的RemoteChannel如何跟某个连接建立对应关系,这一点由PartitionRequestClientFactory来保证。 在NettyConnectionManager类的createPartitionRequestClient方法,连接指定远程分区(connectionId) ,创建远程管道的Handler。创建好之后,会以connectionId 为key存入ConcurrentHashMap。
